Thanks. I did more research. I'm suspicious the problem has to do with my wireless router settings. The tablet will connect to my desktop which is hardwired to my router, but won't connect to the laptop which is wireless. Paul Sinnema's MC Remote article talks about a network access list, mac addresses, and port blocking but it is over my head. I've accessed my router through my desktop but I don't really have any idea what to change.
Any thoughts?
